The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 554-01-8, formula is C5H7N3O, Name is 4-Amino-5-methylpyrimidin-2(1H)-one. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Related Products of 554-01-8.
Yang, Hongmei;Ren, Jing;Zhao, Mei;Chen, Chen;Wang, Fang;Chen, Zilin research published 《 Novel electrochemical immunosensor for O6-methylguanine-DNA methyltransferase gene methylation based on graphene oxide-magnetic nanoparticles-β-cyclodextrin nanocomposite》, the research content is summarized as follows. The detection of methylation level in O6-methylguanine-DNA methyltransferase (MGMT) gene is of great significance for diagnosis, prognosis and treatment of glioblastoma. Herein, we proposed an electrochem. immunosensor for detection of MGMT gene methylation. Graphene oxide-magnetic nanoparticles-β-cyclodextrin (GO-Fe3O4-β-CD) nanocomposite was covered on electrode, and then anti-5-methylcytosine (5mC) antibody was immobilized on modified electrode via host-guest interaction with β-CD. The immobilized antibody specifically recognized and directly captured 5mC on DNA containing MGMT promoter sequence (MGMT-DNA). The methylation level in MGMT-DNA could be evaluated using Ru(NH3)3+6 as an electrochem. signal indicator. The redox recycling of Ru(NH3)3+6 was triggered by Fe(CN)3-6 and further amplified current response. A detection limit as low as 0.0825 pM was obtained. Finally, this electrochem. method was successfully applied to anal. of methylated MGMT-DNA in biol. sample and detection of other methylation modifications, such as N6-methyladenosine in RNA.
Related Products of 554-01-8, 5-Methylcytosine is a methylated form of the nucleobase cytosine occurring predominantly in cytosine-phosphate-guanine (CpG) islands that are produced by DNA methyltransferases and may regulate gene expression. Like cytosine, the DNA sequence containing 5-methylcytosine (5-mC) is able to be replicated without error and 5-mC can pair with guanine in double stranded DNA. However, DNA sequences containing a high local concentration of 5-mC may be less transcriptionally active than areas with higher ratios of unmodified cytosine.
5-Methylcytosine belongs to the class of organic compounds known as hydroxypyrimidines. These are organic compounds containing a hydroxyl group attached to a pyrimidine ring. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5-Methylcytosine exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 5-methylcytosine is primarily located in the cytoplasm. 5-Methylcytosine can be biosynthesized from cytosine. Outside of the human body, 5-methylcytosine can be found in tea. This makes 5-methylcytosine a potential biomarker for the consumption of this food product.
5-methylcytosine is a pyrimidine that is a derivative of cytosine, having a methyl group at the 5-position. It has a role as a human metabolite. It is a member of pyrimidines and a methylcytosine. It derives from a cytosine.
5-Methylcytosine is a nucleic acid that is found in the DNA and RNA of the cell. It is an important component of methylation, which is the process by which a methyl group is added to a molecule. This process can lead to cellular transformation, a process that can cause cancer. 5-Methylcytosine has also been shown as a molecular pathogenesis factor in infectious diseases such as HIV and herpes simplex virus type 1. The presence of 5-methylcytosine in nuclear DNA has been detected by analytical techniques such as gas chromatography/mass spectrometry (GC/MS). There are many analytical methods, including GC/MS, that can be used to detect 5-methylcytosine in cellular nuclei., 554-01-8.
